On December 23, 2016, U.S. Citizenship and Immigration Services' (USCIS) new fees took effect. USCIS published updated versions of the forms. USCIS strongly encourage customers to go to
https://www.uscis.gov/forms to download and submit these new versions, which are updated with the new fees and have an edition date of 12/23/16.
After February 21, 2017, USCIS will no longer accept previous editions of these forms. The complete list of the new fees can be found at
https://www.uscis.gov/forms/our-fees. Applicants must include the new fee or USCIS will reject and return the filing.
